www.gstat.org

Whether planned or not, you just landed at www.gstat.org. This
domain was the main point for the gstat project, which started
in 1993, open sourced in 1997, got a website a bit before 2000,
then remained in Utrecht, where it was taken down in 2014 because
it fell victim to botnet attacks.

where is gstat?

The gstat project started as a source code base from which one
could compile a binary executable that could carry out geostatistical
computations. It started reading and writing pcraster files, then
other file formats were added, until it was linked to the
gdal library.

Since the gstat Rpackage was published
in 2003, development in gstat standalone was constrained to bug fixes only.
Of course both projects share a large C code base, but all
new features happened in R, and no support e.g. for compiling
binaries of gstat standalone took place.

time for retirement?

I don't see any ground to continue development of the gstat standalone
program, and as such it can be considered as retired. Manual and sources of
the original program are still provided.
